Program Inhibit
Programming of multiple M27C801s in parallel with different data is also easily
accomplished. Except for E, all like inputs including GV
common. A TTL low level pulse applied to a M27C801's E input, with V
program that M27C801. A high level E input inhibits the other M27C801s from being
programmed.
Program Verify
A Verify (Read) should be performed on the programmed bits to determine that they were
correctly programmed. The Verify is accomplished with G at V
with t
Electronic Signature
The Electronic Signature (ES) mode allows the reading out of a binary code from an
EPROM that will identify its manufacturer and type. This mode is intended for use by
programming equipment to automatically match the device to be programmed with its
corresponding programming algorithm. The ES mode is functional in the 25°C ± 5°C
ambient temperature range that is required when programming the M27C801. To activate

after the falling edge of E.
